Video Card Power State...

Howdy all. Yes, I'm asking a question this time. I recently bought a Tablet PC that came with Vista Home Premium(Sigh). I made the backup recovery disk and formatted that puppy for XP. Well, I had to fish around for the drivers, which of course, is almost impossible. I went to HP's website and downloaded the XP drivers that are available. Unfortunately they are missing most of their drivers for XP because the computer came with Windows Vista installed. After a day of searching I downloaded all the drivers and everything works, except one, my video card.

I went to www.laptopvideo2go.com and got the drivers there and installed them. All is fine except for one problem. When I leave the laptop around it doesn't go into standby, but the video card does go into power saving mode(D0 to D3). This is where things get complex. When the video card comes out of it's power state I effectively get 2FPS on my desktop, and the screen is no longer at max resolution. It looks like 640x480 stretched to fill my screen. I decided to take a screenshot and save it in paint to see if it looked like crap. Sure enough it's the actual full screen resolution!

Does anyone know of any programs that I can use to force the video driver to go into and out of power states to determine which power state is bad so I can disable it? Or does anyone have any other ideas of things I can try to fix it?
